Nano revolution in data storage

Sarah: Looks like my recent wishes for nanoscale components to make my laptop lighter might not be that far-fetched.  Experts strongly believe that nanotechnology will revolutionise data storage within about 10 years, giving us lighter, more robust and faster computer devices. Computer World and physorg.com both addressed this issue in recent discussions. For example, developments such as Magnetic Random Access Memory (MRAM) could allow components such as the disc drive and memory chip to be merged into one item, making MRAM a likely candidate for becoming the universal memory item in nanoelectronic equipment.  The new development relies on spintronics, whereby the quantum spin of electrons is harnessed to facilitate extremely rapid data stroage and retrieval. Traditional computer storage components rely not on the quantum spin of electrons, but only on their charge.  New material usage will also contribute to novel technologies, such as the changover from silicon to nanoscale metal and carbon components in transistors and electric circuits.  I hate to get all Australian Idol on you…..but that’s what I’m talking ’bout! Love ya Marcia.
